Personal favourite; it's well balanced, so you can use it to at least somewhat fill in whatever slot you need. I have 3 typical builds:
<in game to replace starter>
jolly nature
252 Atk / 128 Def / 128 SpD
-e.q.
-stone edge
Probably hms.
<special tanky, typically doubles>
Calm or timid nature @weakness policy
128 Def / 252 SpA / 128 SpD
-ice beam
-ancient power
-earþ power
-cosmic power
And most splashable:
<singles / setup >
Jolly nature @ light clay
128 Def / 128 SpD / 252 Spe
- light screen
- reflect
- trick room / rapid spin
- explosion
If you go trick room, swap its Spe into Atk and go brave or relaxed nature, depending on what you plan in dropping in behind its fresh screens.
